A blend of diammonium phosphate, magnesium sulfate, yeast hulls and vitamin B complex. Use a 1/2 teaspoon per gallon in wine to stimulate fermentation. Use 1/4 teaspoon per gallon in beer to revive a slow or stuck fermentation. Yeast energizer also works well in meads and honey brews to help create a complete fermentation.

Additional Information

when it arived it was in a pink ziploc bag with several yeast packets and the lid had come loose so there was powder all over everything in the bag, i hope it wasnt contaminated by any bacteria in there, i still used it in a batch of wine and mead, we will see what happens

I've used this in meads to help fermentation begin and it's worked well. Other reviewers have said they use it to help stuck fermentations but I would advise against that. It would be possible to introduce an infection doing that. I'd rather pitch another healthy dose of yeast or dump the batch.

I use this for every batch, just to give the yeast a little help. Since using it the worst I've done is a fermentation that stopped at 1.022, and that might have been because I mash higher. Otherwise it's great.

We've had moderate success using this to revive a stuck beer fermentation. We warm up the beer to 75 add this and gently stir up the trub to re-suspend the yeast. It helps a little, lowering the gravity 0.003 - 0.005.
